I am looking for studies showing differences (or lack of them) in personality (e.g. NEO-FFI, self-control, emotionality etc.) and temperamental traits between adult partners (also parents and partners without children) living in various types of families (nucelar, single-parent, cohabitation, adoptive, foster families).
I am interested if there are some differences between them in this rather constitutive traits and what implications for thinking about various types of family it could bring to us.
Thank you for your suggestions of studies and oppinions about this topic.
